SOU-N D-MODIFYIN' G MEANS FOR TALKING-MACHINES.

To all whom it may concern:

Be it known that I, ELLIS S. 0L1 ER, a citizen of theUnited States, residing at Newarlgin the county of Essex andState of New Jersey, have invented certain new and useful Improvements in Sound-Modifying Means for Talking-Machines; and I do hereby declare the following to 'be a full, clear, and exact description of the invention, such as will enalgle others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to. characters of reference marked thereon, which form a part of this specification;

This invention has reference, generally, to improvements in talking machines and similar sound-reproducing machines, such as the graphophone and the phonograph; and, the present invention relates more particularly to a novel means for use with the usual sound-conveying niemher leading to the reproducing horn, said means being for the purposes of modifying the sounds and by means of the niechanisinvarying to any desired extent the degree of the reproduced sounds.

This invention therefore has for its principal object to providea simply constructed and efficiently operating sound-modifying me ans for use. with the sound-conveying tube or member of the various forms of talkina machines, which is under perfect control or the operator and can be most easily worked, so that the sounds can he reproduced with nodifiedetlects, and especially is this so ith the reproduction of niusicalsounds, as the singing of a person, or a piece played upon a musical instrument or instruments, the pianissimo and forte el'l'rcts being most por fectly reproduced.

Other objects of this invention not at'this time more particularly enumeratedfwill be I clearly understood from the follon' inp ertailed description of my present invention.

The invention consists, primarily, in the novel sound-modifying device-lo use with talking machines-of the various kinds; and the invention consists, furthermore, in the 'l arrangements tlllol COHillllliLtiOIlS of dcr. ano pas -\rr-ll as in'the details of the construct n of the same, all of which Specification of Letters Patent.

Application filed October 31, 1907.

will hr hereinafter more fully described, and

I then finally embodied in the clauses of the claims which are appended to and which form an essential part of this specification.

The invention is-clearly illustrated in the accompanying drawings, in which: Y Figure 1 is a side elevation of one form of talking machine and its sound-conveying tube or member leading to the sound-reproducing horn, a portion of which is shown in elevation, said view showing also in end-elevation the button or operating-member of the sound-modifying means used with saidtulie. Fig. 2 is an enlarged view of said sound-conveying tube or member, shown partly in plan and partly in horizontal section, with an end-portion of the soundn1odi tying means hown in top view, horizontal sectional representation of the jointed elements of said sound-conveying tube or mernlier, with the sound-mmlifying means shown in plan within the joint of said elements; and Fig. 4 is a horizontal section. made on an enlarged scale, of said jointed elements, and of the sound-modifying means arranged in said joint, showing one general arrangement of the parts comprising said sound-modifying means. Fig. 5 is a vertical section taken on line 5- 5 in said Fig. 4, out made on a still larger scale, said section showing the sound-modifying means in its wide-open position within the jointed ele ments of the sound-conveying tube or memher; and Figs. 6 and 7 are similar sectional representations of the same parts, but show in; the sound-modifying means in two of its other positionsfor modifying the sound.

Similar characters of reference are em ployed in all of the above described views, to indicate corresponding parts.
